Rainbow Folders allows you to change the color of selected folder icons. You can use it to navigate your files more efficiently by setting specific colors for important folders, so they are easy to spot in Windows Explorer, open/save dialogs and anywhere else in the file system. In addition, you can also set an extra warning when someone is trying to delete colorized folder (this didn`t work under XP Pro). The program works by modifying the desktop.ini file, so it does not have to be kept running all the time - only add or remove colors from folders.
